What it is
A big button that lights up an LED strip to catch my attention when I’m wearing noise-cancelling headphones and in a zone.
What it’s made of
- Firmware written in C, compiled by the Arduino IDE
- Arduino Pro Micro clone
- Big red button (non-latching) with enclosure
- WS2812B LED strip
- 5v, 4A AC/DC power supply
How it works
Press the button, and an eye-catching pattern fills the LED strip. Much better than getting startled by a co-worker poking my shoulder, or wasting my co-workers’ time by making them wait.
